A buffer circuit is needed to drive the piezoelectric buzzer within a door alarm system. The door mechanism gives a TTL logic well-matched output signal. The buzzer operates from a 12Volt supply and consists of an equivalent load resistance of 80 as well as a small amount of inductance. There is a transistor is obtainable that has a nominal βF of 100. Draw a suitable buffer circuit, describing the rationale of your design and finding the values of all tools used.
